Zitat des Tages von Leonard Susskind:
Whether or not evolution is compatible with faith, science and religion represent two extremely different worldviews, which, if they coexist at all, do so most uncomfortably.
You are a victim of your own neural architecture which doesn't permit you to imagine anything outside of three dimensions. Even two dimensions. People know they can't visualise four or five dimensions, but they think they can close their eyes and see two dimensions. But they can't.
The success of ordinary cosmology speaks against the idea that the universe was created in a random fluctuation.
Science blogs bore me. When everyone is an expert, no one is an expert.
I often feel a discomfort, a kind of embarrassment, when I explain elementary-particle physics to laypeople. It all seems so arbitrary - the ridiculous collection of fundamental particles, the lack of pattern to their masses.
I was from a poor Jewish family in the South Bronx. My father was a plumber, but when I was 16, he got sick and I had to take over. Being a plumber in the South Bronx wasn't fun.
The word 'universe' is obviously not intended to have a plural, but science has evolved in such a way that we need a plural noun for something similar to what we ordinarily call our universe.
I'm doing physics because I'm curious about how it works - full speed ahead, damn the torpedoes, don't worry about whether somebody is going to be able to do an experiment next week, just figure it out.
Eventually, when the universe expands enough, all that will be left is the dark energy.
It seems hopelessly improbable that any particular rules accidentally led to the miracle of intelligent life. Nevertheless, this is exactly what most physicists have believed: intelligent life is a purely serendipitous consequence of physical principles that have nothing to do with our own existence.
At 5 years old, I saw 'Abbott and Costello Meet Frankenstein,' and I was so scared when Costello sat himself down in the lap of the monster, not realizing where he was. My friends teased me. They were older, 8 years old. And my goal was to become a mad scientist and get back at them. And here I am, mad as hell!
Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it? And, you know, everybody has their own idea about what it is, but there's no coherent final consensus on why there is space.
I went to college because my father thought that I should learn engineering, because he wanted to go into the heating business with me. There, I realized I wanted to be a physicist. I had to tell him, which was a somewhat traumatic experience.
Is the universe 'elegant,' as Brian Greene tells us? Not as far as I can tell, not the usual laws of particle physics, anyway. I think I might find the universal principles of String Theory most elegant - if I only knew what they were.
The most important single thing about string theory is that it's a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That's big news.
Life is fragile: it thrives only in a narrow range of temperatures between freezing and boiling. How lucky that our planet is just the right distance from the sun: a little farther, and the death of the perpetual Antarctic winter - or worse - would prevail; a little closer, and the surface would truly fry anything that touched it.
The dark energy is not exactly zero, but the first 122 decimal points are zero. That's crazy. That is really one of the craziest things we've ever discovered.
